How to get the current User when using a general connection user

I have a VB.Net app and a SQL Server 2005 database. Users must login to use
the application, and I have an Employee table to store their details.
However, I use a common user ID to connect to the database (for reasons I
won't go into here).
My problem is, some of my triggers need to know who the current user is, and
of course I can't use the current connection information to get this as I
always get the common user ID.
Does anyone have a technique to solve this dilema? Maybe some way to set a
variable or something when I connect so that I can determine which user has
initiated the connection?You can use application roles to achieve that. Works something like this:
a) Every user has a Windows account using Windows Authentication
b) When they run the application you enable the application role
c) Inside the application's session you can look at what the username is,
including in triggers, using suser_sname()
Hope this helps,
